Sen. Susan Collins’ announcement Friday that she would vote “yes” on Supreme Court nominee Brett Kavanaugh likely ended the uncertainty over his confirmation.

But while Collins spoke on the Senate floor and explained why she would be voting for Kavanaugh, people angry over her decision were donating cash to defeat her in her next election.

More than $50,000 was given over the course of her nearly 45-minute speech, bringing the total raised on an online crowdfunding campaign to defeat Collins in her 2020 election to more than $3 million as of 7 p.m.

The campaign by three activists groups, Be A Hero Team, Maine People’s Alliance and Mainers for Accountable Leadership, had been criticized by Collins and others over several weeks as a possible attempt to bribe Collins into voting against Kavanaugh.

The groups started raising money in August, asking people across the nation to donate to Collins’ opponent in an attempt to show her the stark opposition to Kavanaugh. No one has yet filed to run against Collins in 2020. Susan Rice, former President Barack Obama’s National Security Adviser and United Nations Ambassador, suggested on Twitter Friday that she could challenge Collins.

The donation page, titled “Either Sen. Collins VOTES NO on Kavanaugh OR we fund her future opponent” went down briefly on crowdfunding website crowdpac.com Friday afternoon because of “overwhelming” traffic to the page, Be a Hero said in a statement. The groups are also raising money on the website ActBlue and say in total, between the two the amount has topped $3 million. The groups say donations are coming in every three seconds.

The page has said those donating wouldn’t be charged if Collins voted no on Kavanaugh. But on Friday, Collins seemingly put an end to the uncertainty, giving a nearly 45-minute speech on the Senate floor that explained her process and why she’d be voting to confirm him.

“Susan Collins has betrayed the people, and especially the women and survivors, of Maine,” the campaign organizers said in a statement. “Thousands of Mainers wrote, called, visited, protested, begged and pleaded with Susan Collins to do the right thing – to be a hero – and vote no. She ignored them.”

The statement continued, “For years she has claimed to be an independent, a different kind of Republican, but today she shattered that facade forever. Her vote will reverberate long after she has left the Senate.”
